TWIN STEEL CROSS'IIE.

Application filed November 16, 1926. Serial No. 148,662.

The present invention consists of a combination twin cross tie and rail chair and has for an object to provide a substantial rail support and rail lock which will positively hold the rails from spreading as well as prevent separation of the rails at their ointure.

Other objects of the invention are to provide a combined tie and rail chair equipped with locking wedges to secure the fish plates from displacement; to provide a. chair in which the rails may be conveniently and expeditiously inserted and from which the rails may be readily removed; and toprovide a durable structure which is compact and may be assembled with facility by the ordinary track workers Further objects of the invention will be apparent from the following description of the present preferred form of the invention taken in connection with the accompanying drawings wherein Fig. 1 is a perspective view of a combined cross tie and rail chair constructed in accordance with the presentinvention illustrating its application.

Fig. 2 is a transverse sectional view there of; and

Fig. 3 is a detail fragmentary perspective view showing the rail chair and fish plates from the outside of a single rail.

The device of the present invention embodies a cross tie composed of a pair of I beans 4 preferably made of metal and equipped on their lower faces with right angle anchoring plates 5 which are adapted for penetration in the track ballast in order to prevent longitudinal displacement of the tie. It will be noted that the plates 5 span the distance between the two beams and are secured thereto in proximity to the ends of the beams making up the tie.

Mounted upon the upper faces of the tie are a pair of rail chairs 6 and 7 the former being used where a rail joint exists and the latter being used with a single or integral rail. The rail chair 6 is composed of a base plate 8 which spans the distance between the beams 4 of the tie in parallelism with the angle plates These plates are bolted or otherwise detachably secured to the tops of the beams at and are equipped with superimposed clips 9 and 10. The clips are detachably engaged with the base plate and have the inner marginal edges thereof spaced apart for an appreciable distance to permit the insertion of rails 11 therebetween and likewise accommodate other structure which holds therails to the chair, as hereinafter described. Fish plates 12 are superimposed on the base flanges of the rails 11 at the jointure of the latter and are detachably secured to the rail webs by nuts and bolts 13. It will be noted, especially upon reference to Fig. 2 of the gins of the fish plates are bent outwardly and snugly engage the upper faces of the base flanges of the rails. upwardly over the base portion of the inner fish plate and the innerinarginal edge of the clip bears against the bolt heads to prevent the latter from being casually displaced. The outer'fish plate is engaged by a pair of filler plates 14, the body of each of which overlaps the base of the outer fish plate and thebase flange of the rail and engages beneath the clip 10. It will be'noted that a drawings, that t-helower mar- The clip 9 extends portion 14; of each filler plate is'extended in I wardly to provide a lug 15 which bears against one terminal of the outer fish plate to further prevent longitudinal displacement of the fish plate. The filler plates 14 are secured t0 the base plate 8 of the rail chair by bifurcated keys l6. thekeys being inserted from the bottom of the base plate and having the branches of the bifurcation bent outwardly into engagement with the top of the filler plate. It will be noted, upon reference toFig. 1 of the drawings. that a portion of the web 10 isremoved to provide an opening 17 through which access is gained to the bifurcated ends of the keys. The filler plates 14: slide beneath the nuts 13 the latter from rotation and consequently when it is desired to remove the fish plates it is necessary that the keys 16 be first withdrawn, after which the filler plates 14 are disengaged and the fish plates may then be removed in an obvious manner. Furthermore, the rails may then be disengaged from their chair in an apparent manner.

The rail chair 7 which is only used where the rail is not jointed, embodies a base plate 8 having superimposed clips 9 and 10 detachably mounted thereon. hen this form of chair is employed only outside fish plates 12 are used, the bases of which are elongated, as indicated at 18, so as to extend downwardly into engagement with the top of the base plate 8. The fish plates 12 are secured from displacement by bifurcated keys 16 which are used in the same manner as the keys 16. The clip 10 on the other in order to lock' tial rail supporting SilllCUlIQ" \vhich reduces "to' an absolute minimum the number of ties used, in addition toelimi'nating'the use'ott spikes. The rail-chairs herein used not only support't'he rails on the ties b-nt likewise join together the beams ot'each tie n-nit. Disfplacementotthe railsis prevented, yet the rails may be readily removed: from the chairs when desired.

his to be understood that mrionschanges may be niacle in this invention Within'the scope of the claims hereto-appended.

hat I' claim is lpA device- 215settorth, including acrail chair com-posed of a base plate'with super- I imposed clips, "fish plates shda'ble beneath SZUCl clips and engageable with "the base plate and filler plates slildable beneath certain '01:" sa'id clips inoverlapping engageinentav-1th the fish' plat-es a portioiroii' onetrernnnal' oi each' plate being extended; to limit in- "ward movement of the plate.

A combined rail tie and chairs includ- 111g apanotIbeams-equipped \Vltlt'MIQlG iron anchoring elements on the bottom laces thereof andspanning;- the distancetherebetween, and rail receiving chairs mounted on the upper faces of the beams and secured thereto inparallel relation to the anchoring elements.

A- combined rail tie and chairs includ ing a pair of I beams equipped with angle iron anchoring elements on the bottom faces thereof. rail receiving chairs mounted on the npperi aces ot the beams and secured there to in parallel relation to thewm-aoring elements, fish plates engageal'ile with-said rails "illlClllli the chan'sga'nd filler plates for securing the rails and fish plates to the chairs.

i. Incombination with a rail embraced by fish platesya rail chair includinga base plate with a superimposed-clip having an intern'iediate portion thereof 1'en1oved, a

and fish plate, and means engageable thronghthe base plate-and filler plate-and projecting into the space in the intermedi ate portion of the-clip 'to hold the-filler plates from movement.

5. A device as set forth including a base plate With superimposed -clips,'-fish plates 'slidable' beneath said clips, 1 filler plates interposed between the clips and -fish plates one margin of the outer end of each of which is extended to form a higior limiting the inward movement oi the plate, and

means engaged through the base plate and the inner ends of the'fiher plates to secure the latter from displacei'nent.
